A Virginia woman is facing felony charges after police say she threatened to detonate an explosive device in a convenience store earlier this week.

According to WAVY, 33-year-old Crystal Mostek is accused of walking into a 7-Eleven store near the Bayside Area of Virginia Beach Wednesday night with what turned out to be a dummy bomb.

At the time, however, police say the suspect portrayed the hoax bomb as a serious threat when she approached a clerk at the convenience store on Pleasure House Road at around 8:30 p.m. and placed it on the counter.

Mostek allegedly threatened to blow up the store, as reported by WTKR. As of the latest updates available, it is unclear whether there police have a suspected motive for the crime.

The Virginia Beach Fire Department and local authorities responded to the scene Wednesday evening, where they later determined the device did not contain an actual explosive.

Mostek reportedly pleaded not guilty to criminal counts against her, which include threatening to bomb and possession of a hoax device.

Court records indicate she claimed the charges were fabricated.

Her next scheduled court appearance is in June.

As of the latest reports available, Mostek remained in custody at the Virginia Beach Jail.

Reports indicate her attorney is considering options as part of her defense, such as whether she is in need of treatment for some sort of mental health disorder.
